Part Number: TPD1E04U04
Other Parts Discussed in Thread: ESD321

Could you kindly advise on the functional diagram of TPD1E04U04 ?

The device has two diodes for high-side and low-side and zener diode but ESD321 has only zener diode.

What is the benefit of TPD1E04U04 against ESD321 ?

We would like to know the role of two diodes in TPD1E04U.

Thank you and best regards,

Michiaki

Hello,

They both have the same architecture it is just a different way to represent the same concept.

The difference between them is in the characteristics. I.E. capacitance, clamping voltage etc...

Hello, As I said previously the architecture is the same for both devices even though the diagram is different. The benefit is in the comparison of each or the electrical characteristics.
